Dishwashing liquid (washing-up liquid or fairy liquid in British English), also known as dishwashing soap, dish detergent, or dish soap, is a detergent used in dishwashing. Dishwashing detergent for dishwashers comes in various forms such as cartridges, gels, liquids, packs, powder, and tablets.[1] It is usually a highly-foamy mixture of surfactants with low skin irritation that consumers primarily use for washing glasses, plates, cutlery, and cooking utensils. In addition to its primary use, dishwashing liquid is also used for various informal applications, like creating bubbles, clothes washing, and cleaning off wildlife affected by oil spills. Dishwashing liquid has long existed in various compositions and under different usage conditions.[2][3][4] Currently, most dishwashing liquid functions best with hot water. However, there are some special dishwashing liquids designed to work well with cold water or seawater
